The founders of one startup, MilliLabs , say they’ve found a solution. “Everyone was doing over-the-air testing and we’re saying, ‘Dude, that’s nuts,’” says Aditya Dhananjay , the co-founder and president of MilliLabs. It was widely assumed that emulating millimeter waves was, for all intents and purposes, impossible. Prior to 5G development, standard industry procedure was to use channel emulators to quickly gather a large amount of general dat...
